What are the basic characteristics of the earth s rotation, such as the direction, period, and veloc

The Earth rotates from west to east around its axis of rotation. Earth's rotation is an important form of motion of the Earth, with an average angular velocity of rotation of radian seconds and a linear velocity of rotation at the Earth's equator of 465 meter seconds.

In general, the rotation of the earth is uniform. However, precise astronomical observations have shown that there are three different variations in the Earth's rotation. It takes 23 hours and 56 minutes for the Earth to rotate around and increases or decreases by 3 to 4 thousandths of a second every 10 years.

The Earth's rotation is from west to east, with a period of about 24 hours and a speed of 15° per hour; The revolution period is also from west to east, the cycle is one year, and the speed is about 1° per day.

The rotation of the earth around the earth's axis is called the rotation of the earth, and the direction of the earth's rotation is from west to east, and the period is one day (that is, 24 hours); The earth rotates around the sun constantly, which is called the earth's revolution, and the direction of the earth's revolution is from west to east, and the period is one year

So the answer is: from west to east; One day; from west to east; year

1. The rotation period is moderate to keep the earth stable, and if it is too fast, it will lead to the collapse of the earth; Rotating too slowly makes the Earth's gravitational pull smaller enough to attract the atmosphere, and the Earth's umbrella is gone. 2. The gravitational force of the earth with a moderate orbital period acts as a centripetal force, so that the earth will not be sucked to the sun, and the earth will be subjected to the sun.

Characteristics of the rotation of the earth: the rotational motion of the earth around the earth's axis, and the spatial position of the earth's axis is inherently stable. Its northern end always points near the North Star, and the direction of the Earth's rotation is from west to east.

Characteristics of the earth's revolution: the time required to announce a good key to turn for a week is one year, about a day, and the revolution speed is faster at the perihelion and slower at the aphelion. The Earth's revolution produces seasonal changes in which the seasons alternate, and the average angular velocity of the Earth's revolution is about 1 degree per day.

The movement of the earth around the sun is called the revolution of the earth. Because the earth circles the sun along with other celestial bodies in the solar system, the sun is the central celestial body they share, so it is called "revolution". The direction of the Earth's revolution is from west to east, and the time it takes to complete one revolution is one year.

Phenomena arising from the revolution of the Earth:

1. Changes in the length of day and night;

2. The replacement of the four seasons of spring, summer, autumn and winter;

3. The change of the solar altitude angle at noon;

4. The division of five zones (tropical, north-south temperate zone, north-south cold zone).

The rotation of the earth around the axis of rotation (the Earth's axis) is called the rotation of the earth. The direction of the Earth's rotation is from west to east. From a bird's-eye view of the celestial sphere's North Pole, the Earth's rotation is counterclockwise; Aerial view from the South Pole, is a clockwise rotation.

Phenomena resulting from the rotation of the Earth:

1. The replacement of day and night;

2. The time difference of the place, when there are different places in different longitudes, the longitude is every 15 degrees, and the local time difference is one hour;

3. The deflection force of the earth, the direction of horizontally moving objects is deflected, to the right in the northern hemisphere and to the left in the southern hemisphere;

4. The shape of the earth and the inertial centrifugal force generated by the rotation of the earth make the earth expand from the poles to the equator and become a slightly flattened ellipsoid.

The rotation of the earth around the earth's axis is called the rotation of the earth, and the direction of the earth's rotation is from west to east, and the period is one day (that is, 24 hours);

So the answer is: from west to east; One day;

The direction of rotation, period, and velocity of the Earth.

The period of rotation of the Earth is 23 hours, 56 minutes and 4 seconds, which is one sidereal day, and the time of day and night is 24 hours, which is one solar day.

Characteristics of the Earth's rotational motion: the Earth's rotation around the Earth's axis; The time of one rotation is 24 hours; The Earth rotates from west to east.

Characteristics of the Earth's rotational motion: the Earth revolves around the Sun; The orbit of the Earth's revolution is elliptical; The direction of revolution is from west to east; The time taken for one revolution is one year.
